Canvas cropping outputs blurred

[tobinvadakkedam]

Hai,

Canvas cropping only crops from top left corner,if i give x,y coordinates it will outputs blurred output .if i don't give x,y values, it crops a portion from top left corner correctly.
Caman(canvas, function() {
this.crop(300, 300); // it crops from top left corner
this.crop(300, 300,10,10); // it outputs blurred canvas
this.render();
});
Can anyone help me to solve this issue??
